I don't think I've seen that book given credit for the modern view of Bushido before. However, I have read in multiple places that Bushido is similar to Chivalry in that they were both codified and glorified after the time period in which it supposedly ruled the warrior classes. My suspicion is that Nitobe probably less invented the modern view of Bushido than popularized it for the 20th century (English speaking) audience or at most did a parallel invention of a romanticized view..
